5 1. Introduction As an essential task required by the Cape Cod Metropolitan Planning Organization (MPO) through its Unified Planning Work Program, this report provides the status of pavement condition assessment activities on Cape Cod. The objectives of this effort are to collect data and implement a regional pavement management system for Cape Cod to provide an objective rating of pavement conditions and needs. The pavement management process is conducted with the intent to keep the roadway system in the best possible condition with the most efficient use of available funds. There are distinct advantages to managing pavement condition and significant cost savings that can take place with preventative or rehabilitation measures rather than waiting until a road is in need of reconstruction. As stated in the MPO-approved Cape Cod Regional Transportation Plan, the goal of the pavement management process is for all federal aid-eligible roads to be maintained in excellent condition. Of course, due to the reality of limited financial resources, it is necessary to prioritize pavement repair based on affordability. Deciding which roads to improve and by what technique in a fiscally responsible manner is the essence of Pavement Management. 1.1 PAVEMENT MANAGEMENT SSTEMS - BACKGROUND Pavement Management is the practice of planning for pavement repairs and maintenance with the goal of maximizing the value and life of a pavement network. To accomplish this, a community needs to have several repair techniques in its arsenal and the knowledge of when to apply them. This is where pavement management comes into play. With a comprehensive database of road conditions, the pavement management software can model when to perform which repairs on a road network. Of course, engineering judgment is required to finalize any list of street repairs, as no computer model can take every variable analyzed in making a repair decision into account. The computer system is a great springboard to help a community start its repair program for each year and is an excellent method of storing the repair data. Below is a model of how a street s pavement deteriorates over time. Interpreting the curve, a street starts out in excellent condition when it is newly constructed. Midway through its life, a low cost repair such as crack seal and full depth patch will cost approximately a dollar a square yard. It takes only a few years for the window of opportunity to perform this low cost maintenance to pass after which the road would need an overlay costing $13 - $17 per square yard. By performing timely maintenance, road conditions can be improved today thereby extending the life of the road. Cape Cod Pavement Management Status Report November 2012 Page 1

In both cases observers were given photographs and descriptions of example pavement distresses. Observers used a 1 5 rating system and made notations of particular distresses. Copies of the observations are provided in the appendix of this report. The following table is a summary of the guidance given to observers: November 2012 Cape Cod Pavement Management Status Report Page 2

7 Table 1 - CCC Evaluation Criteria Description Criteria 1 Very Good to Excellent No cracking rutting, raveling/ signs of wear 2 Good to Very Good No cracking, rutting, showing a little wear Showing evidence or more wear and possibly repairs that are in good condition 4 Evidence of cracking, rutting, serious wear 5 Poor Severe cracking, rutting, potholes 1.3 SURVE OF CAPE COD COMMUNITIES PMS ACTIVITIES In early September 2011, and survey was sent to each of the 15 towns Department of Public Works directors. Follow-up inquiries were made in the spring of The survey included the following questions: 1. Do you maintain records of pavement quality on your community s roadways? 2. Can you send [electronically preferred] summaries of pavement quality assessments? 3. What system/method do you use to assess pavement quality? 4. Can you send us a report/documentation of methods used? Cape Cod Pavement Management Status Report November 2012 Page 3

8 5. What method do you use to determine repair strategies? 6. Do you have estimated costs for implementing various repair strategies? 7. Can you forward us cost estimates sheets? 8. Do you have a capital plan for pavement improvement? 9. Can you forward us a copy of the capital plan? Several communities have responded as summarized in the following sections BARNSTABLE PMS ACTIVITIES The of Barnstable utilizes detailed survey and analysis performed by VHB as a Consultant. Their work is entered onto Barnstable s database and periodic reports are provided and discussed. The DPW participates in the data analysis, particularly in the cost analysis. DPW reviews project bids received by the and establishes base line costs for each pavement treatment band, these costs are discussed with the town s consultant - then utilized in the pavement conditions report. In addition to the VHB work, the DPW maintains a record of roadway repairs and relies upon experienced field personnel to assist in planning for individual maintenance tasks such as crack & chip seal. DPW also informally monitors the performance of all treatments. Key to the pavement management program is coordination with other utilities and proposed roadway rehabilitation information is passed to utility companies. A moratorium is in place for 5 years after application of a new surface. The of Barnstable does not maintain a public "5 year plan" - because of political considerations. Submitted materials include: VHB-prepared 2010 Pavement Management Report. See section for discussion of VHB Pavement Management Systems. Excel workbook containing typical costs for various items involved in pavement repair and related road work. November 2012 Cape Cod Pavement Management Status Report Page 4

9 1.3.1 BOURNE PMS ACTIVITIES Bourne is currently doing road resurfacing on an as-needed basis. The town tries to repave four to five miles of roadway each year. In doing that, the town has kept their main roads as their top priority and then broken off into the subdivisions. Bourne does not currently have a capital plan. The town is in discussion with a consultant to look at Bourne s roads and begin working toward a formal pavement management plan DENNIS PMS ACTIVITIES The of Dennis uses VHB s Pavement Management for guidance. The term guidance is used because while VHB keeps Dennis pavement quality records, does field verification on a 1/5th per year basis, grades the town s roads and makes recommendations for repairs, the town has to spend road funds based on several factors that the program is not designed to consider. These local parameters are: some work in each of Dennis 5 villages each year, reconstruction of failed roads, resurfacing of dirt roads and lumping the type of repair to give off-cape vendors enough to give the town a reasonable rate. The town has not had an assessment prepared of estimated costs for various repair strategies for several years. The town s capital plan for pavement improvement allocates $600,000 per year for secondary roads. Chapter 90 funds are used exclusively for primary roads EASTHAM PMS ACTIVITIES The of Eastham is developing a pavement management system. Current efforts include detailed spreadsheets identifying treatment strategies. Submitted materials include: Spreadsheet listing of town roads with summary of face type Spreadsheet listing of & Private s in of Eastham with summary of surface type Spreadsheet listing of town roads with itemized surface type Cape Cod Pavement Management Status Report November 2012 Page 5

10 1.3.2 FALMOUTH PMS ACTIVITIES uses VUEWorks Asset Management Software to track their Public Works Assets. has just begun to use the Pavement rating system that is a module of the system. It is based on the ASTM rating system. has provided a copy of their Pavement Manual, a report of the roads they have rated so far, and a sample report of one of the roads. uses a couple of strategies to determine their repair schedule. The town has a 10-year roadway plan for major repairs. This is funded by the town operating budget and a Capital Plan. has provided both of these documents. The town also has a service call/ work order system to take requests from the public for signs, potholes, sweeping and grading, etc. does not have cost estimate sheets. The town does some work in-house and contracts its crack sealing and large repairs out. These are covered by the town operating budget and Capital Plan. Submitted materials include: Sample Pavement Form VUEWorks Pavement Management System Training Guide F Capital Improvement Program summary form Public Works Department way Maintenance Program F HARWICH PMS ACTIVITIES The of Harwich DPW utilizes an online database that was developed with Bonsai Logic (a small local software developer) to maintain a road inventory, to develop cost estimates, to reconcile DPW estimates against actual expenses and to maintain a roadwork history. The DPW does not utilize the database to develop a PCI (Pavement Index). The town rates roads in 1 of 4 structural conditions: good, fair, deficient, intolerable The DPW does have a 5 year road maintenance plan that is updated every few years and is available on the Harwich website. The town uses Chris Nickerson, Highway Manager who is a certified pavement inspector, to develop a plan based on his experience, training and knowledge of Harwich s 481 public roads (142 miles). The November 2012 Cape Cod Pavement Management Status Report Page 6

11 town attempts to balance maintenance with repair in an attempt to avoid costly reconstruction utilizing many different processes and procedures. For costs, the town utilizes county bid pricing (p. 2 of the town s Five ear Maintenance Plan). Submitted materials include: Summary of roadwork since 2005: excludes any TIP projects F Capital Plan Proposed spending for town capital improvements including pavement maintenance/repair work job examples - Detailed itemized breakdown at pavement repair work at two town locations. 5 ear Maintenance Plan F11-F15 detailed plan of various repair proposals for many town roads, including itemized costs. Harwich Inventory 2010 listing of all town roads. Includes information such as surface width and type, condition (scale of 1 to 4), and length SANDWICH PMS ACTIVITIES The of Sandwich retained the firm of Vanasse Hangen Brustlin (VHB) to perform pavement management services. A comprehensive study was undertaken to re-evaluate pavement conditions in Sandwich and to allow for the analysis of various funding scenarios. VHB performed a detailed inspection of the condition of the pavement on all town-maintained roads and updated a database of this information using VHB s Manager software. To determine road repair strategies, the town mainly uses PCI (Pavement Index) and Benefit. For estimated costs for implementing various repair strategies, the town uses the County s bid process and incorporates these into their own spreadsheets. The town s 5-ear plan changes dramatically year-to-year but provides a guide to follow as funds become available. Submitted materials included the following: VHB Presentation on Sandwich Pavement Management Cape Cod Pavement Management Status Report November 2012 Page 7

VHB services consist of performing a comprehensive study to evaluate pavement conditions in armouth and to allow for the analysis of various funding scenarios; perform a detailed inspection of the condition of the pavement on all town-maintained roads and update a database of this information using VHB s Manager software. To determine repair strategies, the town reviews an initial list generated by the software and then decides whether to apply chip seal, double ship seal, or overlay. Main roads are treated with rubber chip seal or overlay. In the town s capital plan, annual spending ranges from $1.3 million to $1.5 million for roadway maintenance.

13 1.4 SUMMAR OF TOWN PMS EFFORTS Based on responses from the September survey and follow-up in the spring of 2012, the following table summarizes the techniques that responding towns use for pavement management. Table 2 - Summary of Responding s PMS Techniques Pavement Management Technique Barnstable VHB Pavement Management System Bourne Local knowledge as needed basis Dennis VHB Pavement Management System Eastham Locally developed -spreadsheets VUEWorks Asset Management Software Harwich Bonsai Logic way Inventory Sandwich VHB Pavement Management System Truro Local knowledge armouth VHB Pavement Management System VHB PAVEMENT MANAGEMENT SSTEM The most prevalent technique (as identified by many of the towns responding to the survey) is the Pavement Management System developed by Vanasse Hangen Brustlin (VHB). The following sections contain excerpts describing the VHB techniques. These techniques are included in the reports submitted by the various towns: Methodology VHB performed a detailed condition evaluation of each town s public roadways to build the pavement management system. The first step was to identify the roadway network. The second step was to further break each street in the roadway network into pavement management sections. The third step was to carefully categorize, measure, and record the individual pavement distresses within each pavement management section and perform the inventory of sidewalks, curbs, and ramps. Finally, the fourth step was to customize the road repair treatment selection and unit costs within the pavement management software through discussions with officials. All these steps were performed prior to the study of future funding scenarios. Cape Cod Pavement Management Status Report November 2012 Page 9

14 Network Identification Network Identification builds an inventory of streets that describe the municipality s complete roadway network. The direction of travel, street length, width, ownership, classification, zone and pavement type are among the items identified at this initial phase in the pavement management process. This integral step ensures the streets surveyed are the definitive set to be analyzed. Pavement Management Section Identification Once the Network Identification is complete, the field work begins. Each street contains one or more pavement management sections. A pavement management section defines the limits of previous construction or maintenance activities within each street. Sections are defined by having the same width, typical distresses, functional class, etc. The goal is to set up homogenous areas of pavement to aid in assigning the appropriate repair. A street may be one section, or it may be comprised of several pavement management sections, depending on its construction history. Surface Distress Assessment For each pavement management section, the severity and extent of nine major pavement distresses are recorded, and then entered into a weighted formula to arrive at a Pavement Index (PCI). The distresses are categorized as base related or surface related distresses. Base related distresses indicate that the pavement structure is inadequate for the existing traffic load and soil conditions. Streets that show significant base related distresses may need to have the pavement structure strengthened with either thicker or stronger base or pavement materials. Surface related distresses are caused by age and weathering of the pavement. Streets that have predominantly surface related distresses are excellent candidates for maintenance sealing to inhibit further pavement oxidization (the main effect of aging). Streets with more of the base related distresses will most likely need some full depth patching, structural overlays or reclamation/reconstruction. The four base related distresses are: potholing or non-utility patching alligator cracking distortion rutting The five surface related distresses are: block cracking transverse or longitudinal cracking bleeding or polished aggregate surface wear or raveling shoving, slippage or corrugation November 2012 Cape Cod Pavement Management Status Report Page 10

15 PCI Defined A PCI is generated for each inventoried pavement management section in the town using the surface distress data collected by VHB. PCI is measured on a scale of zero to one hundred, with one hundred representing a pavement in perfect condition and zero describing a road in impassable condition. Each type of observed pavement distress is assigned a deduct value based on the type, severity and extent of the distress. A weighted sum of the deduct points is subtracted from the perfect one hundred road in order to generate a PCI for each pavement management section. In general, base related (pavement foundation) distresses are weighted more heavily than surface related distresses. For example, if 15% of a road section had medium severity Alligator Cracking it would receive a deduct of 40 points. Whereas the same area of Block Cracking would only receive a deduct of 15 points. The actual PCI calculation follows: PCI = 100 (Highest Deduct Value) (25% of remaining base related deduct values) (10% of remaining surface related deduct values) Cape Cod Pavement Management Status Report November 2012 Page 11

16 The Five Treatment Bands The pavement management system uses broad ranges to group the individual repair types into five major treatment bands. Treatment bands are a useful tool to summarize data on a -wide basis. An individual road segment will fall into a particular category based on the strategy table s output of repair types and will vary due to functional classification. The goal is to gain a broad understanding of the existing conditions in simple yet meaningful terms. Table 3 - Treatment Band Descriptions TREATMENT BAND PCI* Description DO NOTHING Excellent condition - in need of no maintenance. ROUTINE MAINTENANCE PREVENTIVE MAINTENANCE STRUCTURAL IMPROVEMENT BASE REHABILITATION Good condition may be in need of crack sealing or minor localized repair. Fair condition pavement surface may be in need of surface sealing, full depth patch and/or crack sealing. Deficient condition pavement surface structure in need of added strength for existing traffic. Typical repairs are overlay with or without milling. Poor condition in need of base improvement. Typical repairs are reclamation or full depth reconstruction. *Note: Treatment bands are defined below. These are only general PCI ranges for reference purposes, and represent only one pavement type. There are several fields considered by the strategy table when assigning repair types to each individual street. Source: VHB Do Nothing The Do Nothing category exhibits roads which are in need of no maintenance. These roads are in excellent condition and existing distresses generally do not need to be addressed. November 2012 Cape Cod Pavement Management Status Report Page 12

17 Routine Maintenance Routine maintenance activities are those which are taken to correct a specific pavement distress. Routine maintenance usually addresses localized pavement defects and includes activities such as: Full depth patching; Skin patching; Crack sealing. Preventive Maintenance Preventive maintenance activities are those which are performed at planned intervals to protect and seal the pavement. Seals are designed to provide one or more of the following benefits: Prevent the intrusion of air and moisture; Fill small cracks and voids; Rejuvenate an oxidized binder; Provide a new wearing surface. Structural Improvement Structural improvement includes the work necessary to restore the pavement to a condition that will allow it to perform satisfactorily for several years. Generally a structural improvement will consist of a milling the existing pavement down and applying a new Hot Mix Asphalt Overlay allowing existing grades to be maintained. When the existing grade can be increased a new Hot Mix Asphalt course can simply be placed upon the existing surface. Structural improvements also include the work necessary to prepare the pavement for an overlay, either with or without milling. The major activities involved in the rehabilitation process are: Partial depth patching; Full depth patching; Joint and crack sealing. Grinding and milling Hot Mix Asphalt Leveling Courses. Cape Cod Pavement Management Status Report November 2012 Page 13

18 Base Rehabilitation Base rehabilitation utilizes one of two methods: Reclamation; Reconstruction. Reclamation is the process of rehabilitating existing deteriorated pavements. The existing pavement and base, subbase, and possibly subgrade are pulverized and blended to create a homogenous pavement base. This reclaimed pavement base is then paved with a new Hot Mix Asphalt surface. Reconstruction is the complete removal and replacement of a failed pavement, and might also involve widening, realignment, traffic control devices, safety hardware, and major base and drainage work. Customizing Repair Strategies VHB meet with the DPW to review VHB's typical repair strategies, and to learn how to customize these strategies to meet the 's specific needs. VHB also refines repair unit costs. VHB s goal was to understand the town s decision making process and simulate that process in the budget analysis software based on the pavement condition and other criteria of each pavement section. Preparing Budget Scenarios Once the roadway conditions are inventoried and analyzed, and the repair strategies are defined, the impact of various spending programs on the roadway network is assessed. These studies can range from 1 to 20 years; typically 5-year studies are used. The purpose of the budget planning process is to determine the impact of various spending levels to find a funding level that will best meet the town s needs. The budget analysis software uses pavement deterioration curves, unit costs, and the strategy tables developed in the repair strategy definition phase to assign each street a repair type and associated cost for each year of the study. The software also assigns each street a benefit value that is used to prioritize which streets the software will select for repair each year. It is important to understand that a pavement management system is a network-wide planning tool, and is not intended to give definitive street-by-street repair data. Field verification and testing are recommended to confirm any street repair list generated. Deterioration Curves In order to properly plan for future repairs, the budget analysis feature of the pavement management system uses deterioration curves. The deterioration curves estimate the rate at which the pavement condition decreases over time. These pavement deterioration curves depict two major categories of functional classification - arterials November 2012 Cape Cod Pavement Management Status Report Page 14

19 and collectors in one curve and local roads in the other. An example deterioration curve is presented in the following figure: Figure 2 - Sample Deterioration Curve Source: VHB Strategy Table The pavement management system uses a table of repair strategies to assign specific road repair types to individual roadway segments. The repair strategy table incorporates PCI ranges as well as functional class and pavement type to simulate decisions consistent with Barnstable s repair practices and procedures. Project Prioritization The budget analysis software prioritizes needed system repairs based on the estimated Benefit Value. The Benefit Value formula is calculated using variables representing traffic volume, repair service life, PCI, and unit repair costs for each pavement management section. For each plan year, the software prepares a future roadway condition projection, exhausts the assigned budget, and then produces an annual list of roads included in the repair program. The system also allows the user to enter an inflation rate to account for estimated increases in future year construction costs. A 4% inflation rate is typically used. The Benefit Value prioritization process generally favors cost effective maintenance alternatives. Repair actions are typically delayed on those sections that require reconstruction or major rehabilitation because the benefits for dollars spent are Cape Cod Pavement Management Status Report November 2012 Page 15

20 generally lower than maintenance candidates. After the relatively good roads are "saved," improvements are directed towards the poorer arterial and collector roads, and then to the local roads in need of major rehabilitation. 1.5 ANALSES The data collected in the monitoring process will be continually compared to the measures developed to define congestion. The comparison will be used to identify congested areas and trigger an investigation into the nature of the demand problems MASSDOT EVALUATIONS OF PAVEMENT CONDITIONS As seen in the following table presented in the Cape Cod Regional Transportation Plan, the Cape Cod Region possesses miles of roadway eligible for federal funding. Of those miles, are under the jurisdiction of the Cape s local communities. Table 4 RTP MassDOT Data Available by Jurisdiction MassDOT evaluates roads under their own jurisdiction and a selection of municipallyowned roadways. The following table lists the corresponding rating from Excellent to Poor, based on a PSI rating roughly analogous to the Pavement Index (PCI) commonly used. Pavement Excellent Good Fair Poor PSI Range PSI >=3.5 PSI PSI PSI < 2.3 November 2012 Cape Cod Pavement Management Status Report Page 16

21 The following map identifies the roadways that have been evaluated (shown in red) and those that lack evaluation (shown in blue). Figure 3 - MassDOT Evaluation of Municipal s A recent effort undertaken by the CCC technical staff utilizing recent Massachusetts way Inventory information has identified a slightly lower mileage (80.09) of federal-aid eligible municipal roadways with pavement condition evaluation (vs miles in table above). As seen in the table below, MassDOT way Inventory information is available for miles of federal-aid eligible municipal roadways of those miles are in excellent condition, almost 20.5 miles are in good condition, miles are in fair condition, and about 6.7 miles of evaluated roads are in poor condition. The Geographic Information System pavement file shows 1,040 road segments of varying length evaluated for pavement condition between Over 800 of these segments were evaluated in 2009, less than 200 were evaluated in 2006, and the remainder in Cape Cod Pavement Management Status Report November 2012 Page 17

26 1.5.2 CCC EVALUATIONS OF PAVEMENT CONDITIONS WINDSHIELD SURVES Using the MassDOT pavement evaluation discussed in the previous section as a basis for new data collection, CCC staff undertook a series of Windshield Surveys throughout Barnstable County. Selecting at least one road in each town listed as Municipal s without Evaluation, CCC staff observed pavement conditions according to the criteria in Table 1. Copies of the detailed observations are available in the appendix. The following table provides a summary by town of CCC windshield survey data.

35 1.5.3 CCC EVALUATIONS OF PAVEMENT CONDITIONS ATR SITES Starting in mid-summer of 2011, CCC traffic technicians were tasked with collecting pavement condition data as part of their work in setting up Automatic Traffic Recorders (ATRs). Including data collected in 2012, this yielded pavement condition data at 250 unique locations throughout the Cape s 15 towns. Also, since a 48-hour traffic count was collected from each ATR, results include a Weighted pavement condition for each town. By multiplying the Annual Average Daily Traffic at each location times that locations observed pavement condition, we then totaled these results and divided by the sum of Annual Average Daily Traffic from that town s ATR s. Annual Average Daily Traffic is calculated by multiplying the appropriate MassDOT monthly adjustment factor times the observed average daily traffic over the 48 hour ATR data collection period. The following table presents town-wide averages of the pavement condition information collected at ATR sites. Table 7 - Summary of Pavement s at ATR Sites TOWN # of Sites Avg. AADT Avg.

The following figures are a graphical display of the individual site data for sections of Barnstable County (Upper Cape, Mid- Cape, and Lower Cape). The pavement condition at each ATR site is shown as a colored circle ranging from Blue (Very Good to Excellent) to Red (Poor). November 2012 Cape Cod Pavement Management Status Report Page 32

40 1.5.4 MUNICIPAL EVALUATIONS OF PAVEMENT CONDITIONS Several communities have active PMS and have provided examples of pavement condition reporting. Two of these towns (Barnstable and Sandwich) have submitted maps showing roadways with evaluations of pavement conditions. The color-coding is based on the average Pavement Index (PCI) as described in Section , with the pavement in the best condition (highest PCI) shown in blue and the poorest condition (lowest PCI) shown in red. The Barnstable and Sandwich PCI maps are presented in the following two figures. November 2012 Cape Cod Pavement Management Status Report Page 36

43 1.6 RECOMMENDATIONS FOR ACHIEVING IMPROVED PAVEMENT CONDITION The Regional Transportation Plan included an initial effort at providing a comprehensive county-wide policy for improved pavement condition. The information in this section was originally published in the 2012 RTP. By considering the additional data collected since the 2012 RTP was finalized, more detailed estimates will be available for implementation see discussion in the next section of this report. Based on costs estimated by the Old Colony Planning Council, improving a Good road to Excellent requires $40,400 per mile; improving from Fair requires $405,146 per mile; and improving from Poor requires $697,980 per mile. Improving all of Cape Cod s municipally-owned Federal-Aid roadways to Excellent requires $118,944,832. While Excellent pavement is the ultimate goal of the MPO, this figure is well in excess of the financial constraints outlined in the recently-approved RTP. A strategy is required to responsibly allocate available funding to maintaining and improving pavement condition on Cape Cod. As can be observed by the costs listed above and also demonstrated in Figure 1, allowing pavement to deteriorate to the lowest condition requires a significantly magnified cost to improve. To get closer to the MPO s ultimate goal, resources spent on improving Fair pavement would result in far more miles of resulting Excellent pavement than directing resources to Poor pavement. Nevertheless, Poor pavement cannot be ignored. Therefore, the strategy of the Cape Cod MPO is to evenly divide investment across the lower two categories. Based on expected resources identified in the RTP, the following table lists the resulting totals of each category: Table 8 - Change in Pavement RTP Improvement Strategy Pavement Base Percent Base Miles Improvement Cost Miles Improved New Miles New Percent Excellent 26.40% % Good 32.96% % Fair 26.36% $ 10,367, % Poor 14.28% $ 10,367, % Totals % $ 20,735, % Cape Cod Pavement Management Status Report November 2012 Page 39

44 Implementation of this strategy results in overall improvement of pavement quality. The percentage of Excellent municipally-owned Federal-Aid roadways increases from 26 to 34 percent. Good roadways are maintained at 33%. Fair roadways are reduced from 26 to 22%, and Poor roadways are reduced from 14 to 12 percent. 1.7 CONCLUSION/RECOMMENDATIONS FOR PMS ENHANCEMENT During F 2013, Cape Cod Commission staff will continue advance PMS activities throughout the 15 towns of Barnstable County. Efforts will continue such as: Identify individual towns methods for pavement condition evaluation and programming for improvements Identify gaps in pavement condition information on Municipally-owned Federal Aid eligible roadways and prioritize and implement CCC data collection activities on these roadways Improve CCC skills in performing pavement evaluations Analyze local communities bid prices to develop Cape-specific improvement costs of various pavement conditions November 2012 Cape Cod Pavement Management Status Report Page 40
